Giant cell reparative granuloma (GCRG), which is an uncommon, benign, granulomatous lesion of bone, was first described by Jaffe1 in 1953. It is most commonly found in the mandible but has been reported to occur in many other sites, including the axial skeleton, orbit, sinuses, and cranial vault.1,2 Approximately 35 cases of GCRG originating in the temporal bone have been reported. The lesion has been described in patients ranging in age from 2 months to 72 years.2 The youngest documented patient to date presented with a small palpable mass at the age of 2 months.3 To our knowledge, there are no previous reports of a congenital lesion. Our patient presented with a 4 × 4-cm mass at the age of 5 days, suggesting that the lesion had developed in utero.
